We argue that modern physics—including classical mechanics, relativity, and quantum mechanics—suffers from a fundamental incompleteness rooted in the treatment of time as a variable. Starting from parity violation and the absence of intrinsic lifetime in quantum wave functions, we show that: (1) only matter can observe change, yet physics uses light (which has no time) to define spacetime; (2) the time coordinate is either meaningless (without motion) or not independent (with motion); (3) physics writes equations from a God's eye view but performs measurements from a material observer's view; (4) matter, change, and time form a circular dependency that cannot be resolved within the current framework. The incompleteness of physics is not technical but structural.
